The national park lies within the Napo moist forests ecoregion and is primarily rain forest. The park is about 250 km from Quito and was designated a UNESCO Biosphere Reserve in 1989.
It is within the claimed ancestral territory of the Huaorani indigenous people. Yasuni is home to two uncontacted indigenous tribes, the Tagaeri and the Taromenane.
Yasuni National Park is arguably the most biologically diverse spot on earth. The park is at the center of a small zone where amphibian, bird, mammal, and vascular plant diversity all reach their maximum levels within the western hemisphere.
Moreover, the park breaks world records for local-scale - less than 100 km2
The park holds a world record 150 amphibian species for places with comparable landscapes.
It also is at the top for amphibian diversity compared to other sites sampled in the western Amazon. The total of its amphibian species is more than the United States and Canada combined. Reptile species in the park is also very high with 121 documented species found.
In spite of covering less than 0.15% of the Amazon Basin, Yasuni is home to approximately one-third of amphibian and reptile species.
The park also harbors high levels of fish diversity with 382 known species. This number is greater than the amount of fish species found in the Mississippi River Basin.
Yasuni also is home to at least 596 bird species which comprises one-third of the total native bird species for the Amazon. The park is also rich in species of bats.
On a regional scale, the Amazon Basin has an estimated 117 bat species, but on a local scale, Yasuni is estimated to have comparable richness.
In a single hectare, Yasuni has over 100,000 different species of insects which is roughly the amount of insect species that can be found in all of North America.
The park also boasts one of the world's richest levels of vascular plants. It is one of nine places in the world that has over 4,000 vascular plant species per 10,000 km2.
The park contains many species of trees and shrubs and holds at least four world records for documented tree and liana richness as well as three world records for diversity in woody plant species.
The park also hosts a list endemic species such as 43 different species of vertebrates and 220–720 different plant species. A species of bat, Lophostoma yasuni, is endemic to the park.
Treefrog Osteocephalus yasuni is named after the park.
Yasuni National Park is home to an estimated 1.7 billion barrels of crude oil - 40 percent of Ecuador's reserves – in the Ishpingo-Tiputini-Tambococha (ITT) oil fields.
Environmentalists and scientists such as Jane Goodall, E.O. Wilson, and Stuart Pimm urged the government to leave the resources untapped.
In response, President Rafael Correa launched the Yasuní-ITT Initiative to protect the park's natural resources in June 2007. The initiative promised to leave the park undisturbed in exchange for compensation from the international community.
Not drilling in the park would prevent 400 million metric tons of carbon dioxide from entering the air, officials said.
The government hoped to generate funds of at least 50 percent of the profits that it would receive were it to utilize the oil reserves. In total it hoped that US$3.6 billion would be raised over 12 years.
At the time, the plan was hailed by environmentalists as a precedent setting decision that would reduce the burden of environmental preservation on the world's poorer countries.
Actors Leonardo DiCaprio and Edward Norton, filmmaker and global ecological activist/scientist Michael Charles Tobias, and former Vice President of the United States Al Gore were among those who pledged support to the Ecuadorian government.
Countries contributing funds included Turkey, Chile, Colombia, Georgia, Australia, Spain and Belgium.
However, fundraising efforts were inhibited by Ecuador's insistence that the government alone would decide how any funds raised were spent.
In July 2013, Correa formed a commission to evaluate the Yasuni-ITT initiative's progress to date. The commission concluded that the economic results were not sufficient.
The world has failed us, he said, calling the world's richest countries hypocrites who emit most of the world's greenhouse gases while expecting nations like his to sacrifice economic progress for the environment.
Through an executive order, he liquidated the Yasuni-ITT trust fund formally ending the initiative. During the six-year history of the initiative, only US$336 million had been pledged, Correa said, and of that only US$13.3 million had actually been delivered.
Correa also said he had commissioned economic, legal, and technical studies on drilling in the region in preparation for the national assembly formally opening the park to drilling.
He said expanding Ecuador's oil production was essential to furthering his economic projects that have won him widespread support among the nation's poor.
He said the drilling would affect only 1% of the Yasuni basin. A spokesperson said the drilling could be conducted without damaging the environment. Environmentalists strongly objected to opening the park to oil exploration.
Hundreds of protesters gathered outside the presidential palace after Correa's announcement. Indigenous people and environmentalists called for a national referendum on the issue.
This referendum called the Yasuní-ITT Initiative was enacted in 2007, and by 2009 pledges of support from around the world came to around 1.7 billion dollars.
The money pledged insured that it would be possible to fund the initiative, with support from the international community. Oil production accounts for one-third of Ecuador's national budget.
Colonization, deforestation, illegal logging, and unsustainable hunting are affecting the park at present.
